CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 550,317, dated November26, 1895.

Application filed May 14,1895. Serial No. 549,335. (No model.)

To all whom it may concern:

Be it known that I, HENRY CALLAHAN, of Dayton, county of Montgomery,State of Ohio, have invented a new and useful Improvement inCarburetors; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in carburetors, and has for itsobject to provide means for feeding the hydrocarbon fluid to thegenerator in a systematic and uniform manner, to the end that the use ofvalves or stop-cocks to regulate said feed is dispensed with, thusavoiding a troublesome and undesirable feature in carburetors. Theconstruction and arrangement of the same will be fully described in thefollowing specification, taken in connection with the accompanyingdrawings, of which Figure 1 is a side elevation of the carburetor, theinclosing case being removed from that side to show the relativepositions of the pans. Fig. 2 is a section through the reservoir on theline a CL of Fig. 1. Fig. 3 is an elevation of the reservoir end of thecarburetor.

Similar letters of reference indicate correspondin g parts throughoutthe several views.

A designates the carburetor, comprising a number of receptacles or pansI), placed one above the other, and over each of which are depended rowsof Wicking a or other similar substances which attract the oil andthrough which the air circulates in contact with the oil and the vaporarising therefrom. This is a well-known feature of carburetors, and thearrangement and attachment of said wicking will be made. When the partsare thus united,

they appear as shown in Fig. 1, and are adapted to be inclosed in theground in the usual manner.

provided with floats, valves, &c.

Referring, further, to the reservoir, d designates a number ofstationary pans placed one above the other. These pans are each of asize similar to the evaporating-pans b and are arranged on a horizontalplane therewith that is to say, each of said reservoir-pans (Z is on ahorizontal plane with one of the evaporating-pans and communicatestherewith by means of the tubes e, hereinbefore' referred to. Eachrespective tube 6 lies near the bottom of the pan d, so that they mayconvey the oil from the bottom of said pans. This is essential, asthereby a constant supply of fresh oil is fed to the evaporating-pans,which in sures a more uniform generation and a higher standard of gas.In other words, the purest part of the 0ili. c. that lying on topis notfed to the evaporating-pans first, as is customary, thus leaving theimpurities to accumulate in the bottom to be finally fed to theevaporating-pans; but on the contrary the oil is fed always from thebottom of the pans d, which freshens the supply in said evaporatingpans.Each of the pans d is provided with an overflow-pipe f, that projectsvertically nearly to the top of said pan and communicates with the nextadjacent lower pan.

The capacity of the reservoir may be regulated to feed any desirablenumber of evaporating-pans, and may contain one or more barrels of oil.The oil is introduced through the pipe g, that communicates with theupper reservoir-pan d, from whence it passes to the upperevaporating-pan b. When the oil in both of these upper pans (Z and Z)reaches a plane coincident with the upper end of the overflow-tube f inthe upper pan (1, the oil then passes through said tube to the nextlower pan d, from whence it passes to the next adjacent evaporating-panb, and this operation is repeated until the remaining lower pans d and bare similarly supplied with oil. As the oil in each of theevaporating-pans is consumed, oil passes from the pans (Z in freshquantities, each pan d supplying its respective pan 1) in the mannerstated; By this arrangement of the evaporating-pans it will be seen thata great evaporating surface or area of oil is exposed to the air, andwhich is obtained within a comparatively-small space, as compared withthose carburetors that are For example, a carburetor constructed inaccordance with the foregoing description having, say, fourevaporating-pans, each of which is thirty inches square, will providethree thousand six hundred inches of evaporating-surface.

7L designates a series of suction pipes, which communicate,respectively, with each of the pans (Z and serve to cleanse said panswhenever necessary.

The air is introduced to the bottom evaporating-pan Z) in a well-knownmanner through a pipe 3 and passes upwardly and is carbureted by comingin contact With the hydrocarbon oil. The carbureted air is emittedthrough a pipe 8.

In practice it is desirable to extend the pans Z) and (1 higher thanshown in the drawingsthat is, about one and a half times as high asshown-and to correspondingly lengthen the overflow-tubes f.

I am aware that it is not new to supply a plurality of tanks or panswith liquid by means of overflow-pipes leading from one to the other.Therefore I do not desire to make claim thereto; but my inventionconsists of providing means for uniformly supplying a number ofstationary evaporating pans with oil, said pans occupying a minimumamount of space and aifording a maximum amount of evaporatingsurface,and in which the use of floats and valves is dispensed with.

I claim 1 1. In a carburetor, the combination of a stationary carburetorconsisting of a plurality of communicating evaporating pans arranged oneabove the other, a reservoir of a corresponding size to said carburetorand consisting of a similar number of communicating pans each of whichis on a plane with one of said evaporating pans, a tube connecting eachof said reservoir pans with its adjacent evapcrating pan, said tubeoccupying a position adjacent to the bottom of said pans, substantiallyas and for the purposes specified.

2. In a carburetor, the combination with a plurality of evaporating pansplaced one above the other, of a reservoir adjacent to said evaporatingpans and consisting of a plurality of pans of a size and formcorresponding to said evaporating pans and placed on a horizontal planetherewith, a communicating tube between each of said evaporating andreservoir pans, an overflow tube between each of the reservoir pans, bymeans of which said evaporating pans are uniformly fed with oil from thebottom of the reservoir pans, substantially as described.

In testimony whereof I have hereunto set my hand this 10th day of May,1895.
